Spuds Porting and Tuning Thread

[wyk]

Which Stihl models like being ported and which ones are just not worth while?

 

The MS361 is jokingly called a Husqvarna amongst some porters. It has a similar quad transfer port set up that many newer huskys have. It responds extremely well to porting, especially with machine work. One of my overall favourites ported.

 

Most modern Stihls respond well to porting. They have a less aggressive timing curve than some of the modern Husqvarnas, especially the newer blue coil ones. So they seem to benefit from timing advances more. I rarely advance the timing on saws that I do not own, though. Most people do not notice the difference, especially in the UK where shorter bars are used. Once you run a 28" -32" bar on a 70-80cc powerhead, then small gains in porting make more difference. - especially in compression, timing, and transfer work.

 

From what I have seen, the new 441CM has a whole lot going on inside, and is a bit of a bother to work with compared to most other saws - especially the huskies.

Plug "MS461 Giveaway Saw Build Thread" into Google.

I never realised how much work was involved until I saw that thread! I assumed it was just a couple of holes drilled and some fiddling with screws
